BACKGROUND OF THE INVENTION 1. Field of the Invention

The present general inventive concept relates, in general, to screw type bottle caps used to close any container apparatus and, more particularly, the present general inventive concept relates to a screw type bottle cap having a predetermined substance retained therein which substance is to be dispensed into the contents of the bottle and the cap adapted to fit on bottles having a plurality of different sizes and/or shapes.

2. Description of the Related Art

Prior to the conception and development of the present general inventive concept, as is generally well known in the prior art, screw type caps are in wide spread use throughout the beverage packaging industry. Such screw type bottle caps are used, for example, on water, pop, sport drinks and juice bottles.

The beverage packaging industry utilizes a plurality of different sized and shaped bottles having different sized and shaped bottle-closure devices or bottle caps that to threadably engage each different sized and shaped bottle. Further, the threaded engagements vary.

None of the present day bottle caps which are presently being used have the ability to easily dispense a predetermined substance into the contents of the bottle for any desired purpose. Applicant is aware of some screw type bottle caps which do possess this capability, however, due to their complexity they are not, to the best of applicant's knowledge being used. See, for example, U.S. Pat. Nos. 6,820,740; 6,962,254; 6,569,329; 6,221,416; 7,005,152; 6,165,523 and 5,932,262.

SUMMARY OF THE INVENTION

The present general inventive concept provides, in a first aspect, a bottle cap having a predetermined substance retained therein. The bottle cap is engageable with a bottle containing a preselected beverage therein and having a threaded end for receiving a bottle cap.

Such bottle cap includes a cylindrical member that is closed at a first end thereof and open at a second end thereof. The cylindrical member has each of a first predetermined length and a predetermined inside diameter. There is a threaded portion disposed on an inner surface of the cylindrical member, beginning adjacent such open end and extending inwardly a second predetermined length toward the closed end, for engaging such threaded end of the bottle.

A first means, an internal bladder, is disposed inside the cylindrical member adjacent such closed end thereof for retaining a preselected substance therein to be dispensed into such preselected beverage contained within the bottle. Additionally, a second means, a bladder piercing element, is provided which is engageable with each of such threaded portion of the bottle cap and such first means for retaining the preselected substance for piercing the first means as such bottle cap is threaded onto such threaded portion of such bottle thereby releasing the contents of such first means into such beverage for mixing therewith. The internal bladder stores ingredients such as vitamins, syrup, gas, and/or the like such that the bottle cap delivers the ingredients into the bottle when the bladder is opened by a user.

According to a second aspect, the present general inventive concept provides a bottle cap similar to the embodiment described above except the second means is engageable with each of an upper surface of such bottle and such first means for retaining the preselected substance for piercing such first means as the bottle cap is threaded onto such threaded portion of such bottle thereby releasing contents of the first means into such beverage for mixing therewith. This embodiment of the present general inventive concept further requires a retaining ring which engages with a bottom surface of such second means and an upper surface of such bottle for retaining the second means in position in such bottle cap.

The present general inventive concept is a bottle with bottle cap designed with a multithread closure system to threadably engage the bottle. The bottle may having different thread designs, shapes, and/or sizes. This allows the present general inventive concept to be used with a wide variety of bottles that employ industry standard threads. That is, a multi-thread closure that can be used with existing bottle apparatus that is made as a single, double, and/or triple lead thread design.

The present general inventive concept is designed to overlay a plurality of the current thread standards without any sections having threads that may interfere with each other. In this manner, the present general inventive concept provides a staggered thread design that will adapt by elastically flexing to catch and hold onto a single, double, or triple thread apparatus design in a manner that is sufficient to seal and close the bottle.

It is, therefore, one of the primary objects of the present general inventive concept to provide a screw type bottle cap capable of dispensing a predetermined substance into a predetermined liquid contained in a bottle.

The present general inventive concept also provides a package of screw type bottle caps having a predetermined substance contained therein for screwing onto a bottle coating a predetermined beverage therein and thereafter dispensing such predetermined substance in to such predetermined beverage.

The present general inventive concept also provides a screw type bottle cap having one of preselected flavorings, preselected vitamins and preselected medications contained therein for dispensing into a beverage contained within a bottle.

The present general inventive concept also provides a screw type bottle cap capable of dispensing a predetermined substance into a predetermined liquid contained in a bottle which is relatively inexpensive to manufacture.

The present general inventive concept also provides a screw type bottle cap capable of dispensing a predetermined substance into a predetermined liquid contained in a bottle simple to use.

The present general inventive concept also provides a 3-snap/position lid wherein each snap indicates a step, e.g., 1. secured without bladder penetrated; 2. bladder penetrated; 3. secured with bladder penetrated. The snap may be audible and/or provide physical resistance such that a user is aware of each step 1, 2, and/or 3 during the mechanical twisting that occurs during this function. The threads catch and flex to properly align at the end of the thread tracking to create an adequate seal of the bottle.

The present general inventive concept also provides threading of the cap that fits on different threaded, sized, and/or shaped bottles. 1. The default configuration is the Standard single thread with a 0.125″ pitch; 2. Triple lead thread with a pitch of 0.240″ X one revolution, but it is patterned every 120 degrees around the cap; 3. The “Multi” thread consists of short bits of thread that occur where the other two coincide with one another.

The present general inventive concept may include a manual release lever or button so that the cap contents can be dumped without threadingly engaging a bottle, for instance, into a standard glass, cup, and/or other container that either is not equipped with a threaded receiver to receive the present general inventive concept or is not equipped with a threaded received that will accommodate the present general inventive concept. The lever or button manually moves a bladder opener upward to pierce the bladder and dump the ingredients into a container. The lever may include two tabs that extend from the bladder opener through openings or tracks on either side of the cap such that a user may hold the tabs to secure the bladder opener in place with one hand while the cap is rotated with the other hand. Such movement acts to move the bladder opener toward the bladder end of the cap to pierce the bladder.

Alternatively, the manual release may be surface area on a bottom surface of the bladder opener such that a user may manually push the bladder opener into the bladder seal to open the seal. After the seal is opened, the user may dump the ingredients into a container using gravity and/or shaking the present general inventive concept.

The present general inventive concept may include a seal to contain and/or seal the ingredients in the bladder, e.g. a seal made of a thin metal such as aluminum or a plastic material. In the preferred embodiment, the present general inventive concept is a very brittle aluminum foil that lends itself to breakage. The current method of sealing the seal onto the cap to close the bladder is induction.

The present general inventive concept also provides an axially moving bladder opener that pierces the bladder to dump the contents into a container such as a bottle. The bladder is designed to be pierced in a center thereof such that all of the ingredients are easily emptied into the container leaving no ingredients within the bladder. Such prevents undesired spilling of the ingredients after removal of the cap, e.g., in a pocket of a user if the user is not able to immediately dispose of the cap.

The present general inventive concept also provides a bladder opener with a low profile that is situated under the bladder within the bottle closure device such that a size of the bladder may be maximized to store a larger amount of ingredients therein. Specifically, the bladder design maximizes the amount of space provided within the bottle closure such that over 50% of the space provided within the bottle closure is ingredient storage area.

The present general inventive concept also provides an opening in an upper side of the cap, such as a spout, such that upon engagement to a bottle and release of contents within the cap, the spout may be selectively opened by pulling the spout away from the bottle and/or selectively closed by pushing the spout toward the bottle, such that when the spout is open, the contents may exit the bottle, e.g., for consumption by a user and the like, without removing the cap yet and when the spout is closed, the contents are securely stored within the bottle, e.g., for mixing, storage, and the like.

DETAILED DESCRIPTION OF THE INVENTION

Prior to proceeding to the more detailed description of the present general inventive concept it should be noted that, for the sake of clarity and understanding, identical components which have identical functions have been identified with identical reference numerals throughout the several views illustrated in the drawing figures.

Reference is now made, more particularly, to FIGS. 1-3 of the drawings. Illustrated therein is a presently preferred embodiment of a bottle cap, generally designated 10. The bottle cap 10 is preferably formed from plastic and has a predetermined substance retained therein. Such bottle cap 10 is selectively engageable with a plurality of different sized and/or shaped bottles such as bottle 12 (see FIG. 5) containing a preselected beverage therein and having a threaded end 14 (see FIG. 5) for receiving the bottle cap 10.

The bottle cap 10 is a cylindrical member 16 closed at a first end 18 thereof and opened at a second end 20 thereof. The cylindrical member 16 has each of a first predetermined length and a predetermined inside diameter.

A threaded portion 22 is disposed on an inner surface 24 of the cylindrical member 16, beginning adjacent such open end 20 and extending inwardly for a second predetermined length toward the closed end 18, for engaging such threaded end 14 of the bottle 12.

The threaded portion 22 is designed such that the bottle cap 10 can mate with two or more bottles each having a different thread design. For instance, a first bottle may have a single lead thread design, a second bottle may have a double lead thread design, and a third bottle may have a triple lead thread design, each mateable with the bottle cap 10.

In one embodiment, the threaded portion 22 consists of a first portion and a second portion.

The first portion of the bottle cap 10 has a thread pitch of 0.135″, a thread start point 0.060″ upwards from a bottom edge of the bottle cap 10, and a thread duration of 1.1revolutions.

The second portion of the threaded portion 22 of the bottle cap 10 has a thread pitch of 0.125″, a thread start point 0.185″ upwards from a bottom edge of the bottle cap 10, and a thread duration of 1.3 revolutions.

In combination, each of the first and second portions of the threaded portion 22 have a width of 0.050″, a thread height of 0.045″, a major diameter inside of the bottle cap 10 of 1.090″, a minor diameter of a thread from peak to peak of 1.000″, and a total of 8 separate thread segments.

As illustrated in FIGS. 13-22, the present general inventive concept consists of five different sections or profiles.

The first profile illustrated in FIGS. 13 and 14 has a thread height to 0.050″, a thread width of 0.045″, a distance upward to a center of the profile of 0.040″, a helix start angle of 90 degrees, a helix duration of 0.2 revolutions, and a helix pitch of 0.175″.

The second profile illustrated in FIGS. 15 and 16 has a thread height to 0.050″, a thread width of 0.045″, a distance upward to a center of the profile of 0.100″, a helix start angle of 285 degrees, a helix duration of 0.32 revolutions, and a helix pitch of 0.180″.

The third profile illustrated in FIGS. 17 and 18 has a thread height to 0.050″, a thread width of 0.045″, a distance upward to a center of the profile of 0.180″, a helix start angle of 164 degrees, a helix duration of 0.32 revolutions, and a helix pitch of 0.175″.

The fourth profile illustrated in FIGS. 19 and 20 has a thread height to 0.050″, a thread width of 0.045″, a distance upward to a center of the profile of 0.260″, a helix start angle of 45 degrees, a helix duration of 0.32 revolutions, and a helix pitch of 0.175″.

The fifth profile illustrated in FIGS. 21 and 22 has a thread height to 0.025″, a distance upward to a center of the profile of 0.040″, a helix start angle of 90 degrees, a helix duration of 0.075 revolutions, and a helix pitch of 0.240″.

Further, there is a first means, generally designated 30, disposed inside such cylindrical member 16 adjacent such closed end 18 thereof for retaining the predetermined substance therein which is to be dispensed into such preselected beverage contained within the bottle 12. Such first means 30 is preferably a capsule 26.

A second means, generally designated 40, is engageable with each of such threaded portion 22 of the bottle cap 10 and such first means 30 retaining such preselected substance for piercing such first means 30 as the bottle cap 10 is threaded onto such threaded portion of such bottle 12 thereby releasing the contents of such first means 30 into such beverage for mixing therewith. In the presently preferred embodiment of the present general inventive concept such second means 40 includes a pyramid shaped upper portion 28.

Such second predetermined length of the threaded portion 22 is at least sufficient to force such second means 40 up far enough to pierce the first means 30.

In the preferred embodiment of the present general inventive concept, the predetermined substance is selected from the group consisting of preselected flavors, liquid vitamins and liquid medications. Such preselected flavors are selected from the group consisting of cherry, strawberry, butterscotch, vanilla, chocolate, raspberry, lemon, lime and orange. The liquid vitamins are multi-vitamins and baby vitamins. The liquid medications include aspirin, cough medicine and antibiotics. Additionally, the preselected beverages include water, juices and soda.

Reference is now made more particularly to FIGS. 3-6. Illustrates therein is an alternative embodiment of a bottle cap, generally designated 10, having a predetermined substance retained therein. As described above, in the first embodiment, the bottle cap 10 is engageable with a bottle 12 containing a preselected beverage therein and having a threaded end 14 for receiving the bottle cap 10.

In this embodiment of the present general inventive concept, each of the cylindrical member 16, the threaded portion 22 and the a first means 30 disposed inside such cylindrical member 16 are the same as in the embodiment provided supra.

However, in this embodiment, there is a second means, generally designated 50, which engages with each of an upper surface 32 of such bottle 12 and such first means 30 for retaining the preselected substance for piercing the outer surface of first means 30 as such bottle cap 10 is threaded onto such threaded portion 14 of such bottle 12 thereby releasing the 20 contents of such first means 30 into such beverage for mixing therewith.

In this embodiment of the present general inventive concept there is a retaining ring 34 that engages with a bottom surface 36 of such second means 30 and an upper surface 32 of such bottle 12 for retaining such second means 50 in position in such bottle cap 10 to pierce a capsule 26 containing a predetermined substance selected from the group consisting of preselected flavors, liquid vitamins and liquid medications. The presently preferred preselected flavors, liquid vitamins and liquid medications are the same as the ones discussed above with respect to the first embodiment.

Likewise in this second embodiment, the preselected beverages include water, juices and soda. Also the second predetermined length of such threaded portion 22 is at least sufficient to force such second means 50 up far enough to pierce such first means 30.

FIGS. 31-33 illustrate a spout 300 having an opening 310, such that upon engagement to a bottle and release of contents within the bottle cap 10, the spout 300 may be selectively opened by pulling the spout 300 away from the bottle and/or selectively closed by pushing the spout 300 toward the bottle, such that when the spout 300 is open, the contents may exit the bottle, e.g., for consumption by a user and the like, without removing the bottle cap 10 yet and when the spout is closed, the contents are securely stored within the bottle, e.g., for mixing, storage, and the like. It is foreseen that the spout 300 may also be opened and/or closed by twisting the spout 300 in a clockwise direction to close and a counterclockwise direction to open.

The spout 300 may also have its own cap 320 to provide a barrier between the spout 300 and unwanted debris. It is foreseen that the cap 320 may be designed to open and close the spout 300 such that when the cap 320 engages the spout 300, the cap seals the aperture 310, and when the cap 320 disengages the spout 300, the cap unseals the aperture 310.

The present general inventive concept also provides an opening in an upper side of the cap, such as a spout, such that upon engagement to a bottle and release of contents within the cap, the spout may be selectively opened by pulling the spout away from the bottle and/or selectively closed by pushing the spout toward the bottle, such that when the spout is open, the contents may exit the bottle, e.g., for consumption by a user and the like, without removing the cap yet and when the spout is closed, the contents are securely stored within the bottle, e.g., for mixing, storage, and the like.

While a presently preferred and various alternative embodiments of the present general inventive concept have been described in sufficient detail above to enable a person skilled in the relevant art to make and use the same it should be obvious that various other adaptations and modifications can be envisioned by those persons skilled in such art without departing from either the spirit of the present general inventive concept or the scope of the appended claims.
